Can figure numbers be re-assigned?

Is it possible to re-assign a figure number , for example if I have a Figure 55 open, can I make it Figure 2 as long as I don't already have a Figure 2 open? If so how do I do this?
I have a routine that generates 60+ figures, and I delete all but 3 interesting ones. I would like to make them Figures 1,2,3 because I need to re-run the routine and generate another set of figures, and I'd like the first set to appear together in the figure order (it makes them easier to keep track of).

To get a list of all the existing figures:
get(0,'Children');
If figure two does not exist and you want to copy figure(55):
figure(2)
copyobj(allchild(55),2);
Get rid of figure(55):
clf(55);
And to answer your question directly. I believe once a figure number is set, you have to live with it. But there are workarounds, such as the one above.

This maybe a bit hard to implemented based on how you're selecting the 3 interesting ones but the function copyobj() will do the trick.
x = randi(10,1,5);
h1 = figure(1),plot(x);
figure(100);
h2 = gcf;
copyobj(allchild(h1),h2);
Here i create a random plot in figure 1. and then using gcf i get figure 100 and copy figure 1 to figure 100.

The only reliable way that I have found, one which avoids copyobj and keeps all the figure formatting, is to save all open figures to a temporary .fig file and then reload i. The reloaded figures will always be numbered sequentially starting at the first available fig number.
H=findobj(groot,'Type','figure'); %Get all open figures
tn=tempname('.')+".fig"; %generate temporary name
savefig(H,tn)
close all
openfig(tn); delete(tn);
